was wandering if you could help me with the age and where it was made, serial # is 761xxx, and also is it a feather weight thank you

Now that looks to be an interesting rifle. From the research I've done, 761,xxx serial numbers were/are from rifles made in 1965, making it a post '64 rifle. But in 1965 the Featherweight version (22" barrel and no barrel band for rear sight) was no longer being produced (best of my knowledge). The Featherweight came back in the early to mid eighties with the Featherweight XTR model.

If you don't mind my asking, what makes you think it is a featherweight? Does it have the word "Featherweight" stamped on the barrel?
